BackgroundThe dural puncture epidural technique has been shown in some studies to improve the onset and quality of the initiation of labor analgesia compared with the standard epidural technique. However, few studies have investigated whether this technique confers advantages during the maintenance of analgesia. This randomized double-blinded controlled study compared dural puncture epidural analgesia with standard epidural analgesia when analgesia was maintained using programmed intermittent epidural boluses.Methods400 parturients requesting epidural labor analgesia were randomized to have analgesia initiated with a test dose of 3 mL lidocaine 1.5% with epinephrine 15 µg, followed by 12 mL ropivacaine 0.15% mixed with sufentanil 0.5 µg/mL using the dural puncture epidural or the standard epidural technique. After confirming satisfactory analgesia, analgesia was maintained with ropivacaine 0.1% and sufentanil 0.5 µg/mL via programmed intermittent epidural boluses (fixed volume 8 mL, intervals 40 min). We compared local anesthetic consumption, pain scores, obstetric and neonatal outcomes and patient satisfaction.ResultsA total of 339 patients completed the study and had data analyzed. There were no differences between the dural puncture epidural and standard epidural groups in ropivacaine consumption (mean difference −0.724 mg, 95% CI of difference −1.450 to 0.001 mg, p=0.051), pain scores, time to first programmed intermittent epidural bolus, the number of programmed intermittent epidural boluses, the number of manual epidural boluses, obstetric outcome or neonatal outcome. Patient satisfaction scores were statistically higher in the dural puncture epidural group but the absolute difference in scores was small.ConclusionOur findings suggest that when labor analgesia is maintained using the programmed intermittent epidural bolus method, there is no significant advantage to initiating analgesia using the dural puncture epidural compared with the standard epidural technique.Trial registration numberChiCTR2200062349.

Objective: Continuous thoracic epidural analgesia (TEA) is compared with erector spinae plane (ESP) block for the perioperative pain management in patients undergoing cardiac surgery for the quality of analgesia, incentive spirometry, ventilator duration, and intensive care unit (ICU) duration. Methodology: A prospective, randomized comparative clinical study was conducted. A total of 50 patients were enrolled, who were randomized to either Group A: TEA (n = 25) or Group B: ESP block (n = 25). Visual analog scale (VAS) was recorded in both the groups during rest and cough at the various time intervals postextubation. Both the groups were also compared for incentive spirometry, ventilator, and ICU duration. Statistical analysis was performed using the independent Student's t-test. A value of P < 0.05 was considered statistically significant. Results: C omparable VAS scores were revealed at 0 h, 3 h, 6 h, and 12 h (P > 0.05) at rest and during cough in both the groups. Group A had a statistically significant VAS score than Group B (P ≤ 0.05) at 24 h, 36 h, and 48 h but mean VAS in either of the Group was ≤4 both at rest and during cough. Incentive spirometry, ventilator, and ICU duration were comparable between the groups. Conclusion: ESP block is easy to perform and can serve as a promising alternative to TEA in optimal perioperative pain management in cardiac surgery.

Compare transversus abdominis plane (TAP) blocks with liposomal bupivacaine were to epidural analgesia for pain at rest and opioid consumption in patients recovering from abdominal surgery. ERAS pathways suggest TAP blocks in preference to epidural analgesia for abdominal surgery. However, the relative efficacies of TAP blocks and epidural analgesia remains unknown. Patients having major abdominal surgery were enrolled at six sites and randomly assigned 1:1 to thoracic epidural analgesia or bilateral/4-quadrant TAP blocks with liposomal bupivacaine. Intravenous opioids were used as needed. Non-inferiority margins were a priori set at 1 point on an 11-point pain numeric rating scale for pain at rest and at a 25% increase in postoperative opioid consumption. Enrollment was stopped per protocol at 3rd interim analysis after crossing an a priori futility boundary. 498 patients were analyzed (255 had TAP blocks and 243 had epidurals). Pain scores at rest in patients assigned to TAP blocks were significantly non-inferior to those given epidurals, with an estimated difference of 0.09 points (CI: −0.12, 0.30; noninferiority P < 0.001). Opioid consumption during the initial 3 postoperative days in TAP patients was not non-inferior to epidurals, with an estimated ratio of geometric means of 1.37 (CI: 1.05, 1.79; non-inferiority P = 0.754). However, the absolute difference was only 21 mg morphine equivalents over the 3 days. Patients with epidurals were more likely to experience mean arterial pressures <65 mmHg than those given TAP blocks: 48% versus 31%, P = 0.006. Pain scores at rest during the initial three days after major abdominal surgery were similar. Patients assigned to TAP blocks required more opioid then epidural patients but had less hypotension. Clinicians should reconsider epidural analgesia in patients at risk from hypotension.

To test the hypothesis that thoracic epidural anesthesia and analgesia (TEA) reduces the incidence of chronic postoperative pain (CPSP) after video-assisted thoracoscopic surgery (VATS). A single-center, single-blind, randomized controlled trial was conducted. The study was conducted in the operating room, with follow-up assessments performed in the ward. Telephone was used to follow the long-term outcomes. 231 patients ≥18 years of age and scheduled for VATS. Patients were randomized into two groups, including an epidural block (EPI) group (general anesthesia with patient-controlled epidural analgesia) and a general anesthesia with patient-controlled intravenous analgesia (PCIA) group. The primary endpoint was the incidence of CPSP at 3 months postoperatively. CPSP data, including acute pain, neuropathic pain, depression, and side effects, were collected at 3 and 6 months postoperatively through telephone follow-up. A total of 231 patients were analyzed, including 114 in the PCIA group and 117 in the EPI group. Sixty-six patients (56.4 %) in the PCIA group and 33 patients (28.9 %) in the EPI group experienced chronic pain at 3 months postoperatively. The odds ratio (OR) was 0.31 (95 % confidence interval [CI], 0.18 to 0.54; P < 0.0001). After adjusting for confounding factors, the adjusted OR was 0.28 (95 % CI, 0.16 to 0.50, P < 0.001). Six months postoperatively, 50 (42.7 %) and 17 (14.9 %) patients in the PCIA and EPI groups, respectively, were diagnosed with CPSP (P < 0.0001). •Thoracic epidural analgesia can reduce the incidence of chronic pain after VATS.•Thoracic epidural analgesia can reduce the severity of acute pain after 24 h of VATS.•Thoracic epidural analgesia should be superior considered for patients with high risks of CPSP.

Shortening analgesic onset has been researched and it has been documented that prewarming epidural medications to body temperature (37°C) prior to administration increases medication efficacy. Our double-blind randomized controlled trial was designed to investigate if a lower degree of prewarming in providers’ pockets could achieve similar results without the need of a bedside incubator. A total of 136 parturients were randomized into either the pocket-warmed group or the room temperature group to receive 10 mL of 0.125% bupivacaine with 2 μg/mL fentanyl epidural bolus at either the 27.8 ±1.7°C or 22.1 ±1.0°C temperatures, respectively. Primary outcome, time to analgesic onset (verbal rating scale pain score ≤ 3) was recorded in 0-, 5-, 10-, 15-, 20-, 30-, and 60-minutes intervals. It was observed that the pocket-warming group (n = 64) and room temperature group (n = 72) had no significant difference of analgesic onset time (median 8 vs. 6.2 minutes; p = 0.322). The incidence of adverse events such as hypotension, fever (≥ 38°C), nausea, vomiting, and number of top-off epidural boluses, as well as patient satisfaction rates and mode of delivery, were not significantly different between the groups as well. Further research is warranted to confirm these findings and explore the impact of different temperatures on analgesic onset time as well as the logistical issues associated with their clinical implementations.

Background Abnormal cardiotocogram (CTG) tracing may appear after induction of neuraxial labor analgesia. Non-reassuring fetal status (NRFS) indicated by severely abnormal tracings, such as prolonged deceleration (PD) or bradycardia, can necessitate immediate operative delivery. Combined spinal epidural analgesia (CSEA) is known to result in more frequent abnormal tracings than epidural analgesia (EA); however, the corresponding data related to dural puncture epidural (DPE) are unclear. We aimed to evaluate the rates of incidence of severe abnormal CTG after induction of DPE and CSEA. Methods In this study of nulliparous women with full-term pregnancy, data for the DPE intervention group were prospectively collected, while those for the CSEA control group were obtained from medical records. Neuraxial analgesia was performed with cervical dilation ≤ 5 cm, administering initial epidural dosing of 15 mL of 0.125% levobupivacaine with fentanyl 2.5µg/mL for DPE, and intrathecal 0.5% bupivacaine 2.5 mg (0.5ml), fentanyl 10 µg (0.2ml), and 1.3 mL of saline for CSEA. The primary outcome was the incidence of PD, defined as a fetal heart rate reduction ≥ 15 bpm below the baseline and with a lowest value < 80 bpm, and lasting for ≥ 2 min but < 10 min (fetal heart rate < 80 bpm does not have to last for ≥ 2 min), within 90 min after induction of neuraxial labor analgesia. Results A total of 302 patients were analyzed, with 151 in each group. The incidence of PD after DPE induction was significantly lower than that after CSEA induction (4.0% vs. 14.6%, P  = 0.0015, odds ratio = 0.243, 95% confidence interval = 0.095–0.617). Conclusion DPE appears to be a safer method compared to CSEA for neuraxial labor analgesia in the early stages of labor for nulliparous women. Trial registration UMIN-CTR: UMIN000035153 .

To the Editor, Identification of bony landmarks by palpation can be difficult in obese pregnant women, and obesity is associated with higher epidural catheter failure rates [1]. Ultrasound may help offset the challenges of epidural catheter placement in obese patients [2], but few studies have compared it to landmark palpation in morbidly obese (body mass index, BMI ≥40) patients. In the palpation group, there were two cases of paresthesia during epidural needle placement, one unilateral block requiring catheter adjustment (epidural catheter pulled back 1 cm, no reinsertion required), and one unintentional dural puncture resulting post-dural puncture headache (declined epidural blood patch).

Background and objectivesThe evolving surgical techniques in thoracoscopic surgery necessitate the exploration of anesthesiological techniques. This study aimed to investigate whether incorporating a continuous erector spinae plane (ESP) block into a multimodal analgesia regimen is non-inferior to continuous thoracic epidural analgesia (TEA) in terms of quality of postoperative recovery for patients undergoing elective unilateral video-assisted thoracoscopic surgery.MethodsWe conducted a multicenter, prospective, randomized, open-label non-inferiority trial between July 2020 and December 2022. Ninety patients were randomly assigned to receive either continuous ESP block or TEA. The primary outcome parameter was the Quality of Recovery-15 (QoR-15) score, measured before surgery as a baseline and on postoperative days 0, 1, and 2. Secondary outcome parameters included pain scores, length of hospital stay, morphine consumption, nausea and vomiting, itching, speed of mobilization, and urinary catheterization.ResultsAnalysis of the primary outcome showed a mean QoR-15 difference between the groups ESP block versus TEA of 1 (95% CI −9 to –12, p=0.79) on day 0, –1 (95% CI −11 to –8, p=0.81) on day 1 and −2 (95% CI −14 to –11, p=0.79) on day 2.ConclusionsThe continuous ESP block is non-inferior to TEA in video-assisted thoracoscopic surgery.Trial registration numberDutch Trial Register (NL6433).

PurposeAssessment of sensory block level during labour epidural analgesia is an essential component of clinical practice and patient safety. Nevertheless, the methods and direction of testing are not standardized. In our hospital, sensory block testing to ice is routinely used, but while some anesthesiologists test the block from a nonanesthetized to an anesthetized area, some do it in the opposite direction. It is unknown how these two different practices affect identification of the sensory block level. The objective of this study was to determine the agreement between these two practices.MethodsWe enrolled 31 patients admitted to the labour and delivery unit in a prospective cohort study. At their request, labour epidural analgesia was performed as per institutional routine. Sensory block level to ice was assessed using opposite directions by two randomly assigned independent investigators, one and two hours after the loading dose was administered.ResultsSensory block levels to ice assessed from an anesthetized area to a nonanesthetized area were lower than those when assessed with the stimulus applied in the opposite direction, typically one segment lower.DiscussionGiven the small difference detected with both methods, it may be acceptable to use either in clinical practice. Nevertheless, the lack of standardization may have a significant impact when comparing studies involving assessment of sensory block to ice.Study registrationwww.ClinicalTrials.gov (NCT03572439); registered 28 June 2018.

Background and objectivesTo investigate the possible effect of postoperatively applied analgesics—epidurally applied levobupivacaine or intravenously applied morphine—on systemic inflammatory response and plasma concentration of interleukin (IL)-6 and to determine whether the intensity of inflammatory response is related to postoperative cognitive dysfunction (POCD).MethodsThis is a randomized, prospective, controlled study in an academic hospital. Patients were 65 years and older scheduled for femoral fracture fixation from July 2016 to September 2017. Inflammatory response was assessed by leukocytes, neutrophils, C reactive protein (CRP) and fibrinogen levels in four blood samples (before anesthesia, 24 hours, 72 hours and 120 hours postoperatively) and IL-6 concentration from three blood samples (before anesthesia, 24 hours and 72 hours postoperatively). Cognitive function was assessed using the Mini-Mental State Examination preoperatively, from the first to the fifth postoperative day and on the day of discharge.ResultsThe study population included 70 patients, 35 in each group. The incidence of POCD was significantly lower in the levobupivacaine group (9%) than in the morphine group (31%) (p=0.03). CRP was significantly lower in the levobupivacaine group 72 hours (p=0.03) and 120 hours (p=0.04) after surgery. IL-6 values were significantly lower in the levobupivacaine group 72 hours after surgery (p=0.02). The only predictor of POCD in all patients was the level of IL-6 72 hours after surgery (p=0.03).ConclusionsThere is a statistically significant association between use of epidural levobupivacaine and a reduction in some inflammatory markers. Postoperative patient-controlled epidural analgesia reduces the incidence of POCD compared with intravenous morphine analgesia in the studied population.Trial registration numberNCT02848599.
